COMBINED BAND-KNIFE INSEAIVI-TRIMMING MACHINE AND WELT-POUNDING DEVICE.

TO all whom it may concern Be it known that I, \VILLIAM B. Karen may, a citizen of the United States, and a resident of Vineland, Cumberland county,

ew Jersey, have invented certain Improve- .and pounding or beating the welts thereof;

it being particularly desired that the ma chine shall be simple and substantial in construction as well as etticient in action, and have its parts so arranged as to render possible a high speed of operation.

I Another object of the invention to provide novel mechanism for feeding a-shoe to be trimmed to a band knife or other form of cutter; it being furtherdesired that the machine shall include novel means for causing a hammer to pound or tlatten the welt of a shoe while itis being trimmed by this particular form of cutter.

I also desire to provide a welt beating attachment. for an inseam trimmer with improved means whereby it is possible to pound or flatten the welt at the same time it is being trimmed by the knife or cutter, Without interfering with the action of the latter; the

invention also contemplating a novel device for adjusting the parts of the apparatus to permit of the introduction or entrance of the work. I i r I further desire to provide a device of the character described with novel means for su )Jortin a shoe while it is beiu simultaneously acted on by an inseam trimmer and a welt beater; the invention also contemplating improved means for taking up the force of the blows of the hammer.

These objects and other admntageous ends I secure as hereinafter set. forth, refer-- ence being bad to the accompanying drawings, in which v vl*i ;lir( 1, is a front elevation of a machine constructed according to my invention; Fig. 2, is a side elevation of the machine shown in Fig. 1; Fig. 3, is a plan partly in section on the line a-a, Fig. 1; Fig. 4-,is an enlarged horizontal section on the line ?)b, Fig. I;

Fig. 5, is a front elevation on an enlarged Specification of Letters Patent.

scale showing the detail arrangement of cer" tain of the parts of the machine, and Fig. (i, is an end elevation of the hammer.

In the above drawings, 1 represents a por tion of the main supporting frame of the machine constituting my invention which,

has a .vertical post 2, and a pair of stand ards 3 andxt which carry a transverse member 5 having mounted on it a work supporting post (3 supportedin a slideway so as to be movable toward and from the front of the machine. There is also a band knife or cutter 7 shown in Figs. 1 and 2 and whose second vertical run is shown in Fig. 3 at 7. The work supporting post 6 has its top downwardly inclined away from the knife 7, be-

cable bar 9 held in place by a cover plate 9 and abutting on an adJustable vibratory defront face and in this slides a block 8 yieldingly ,SUPPOI'tQd on a spring 8 which is p0- sitioned by a pin 8? carried by a structure projecting from said post 6. On the upper end ofthe block '8 is mounted a work supporting saddle 10 fornud with a vertical plane face immediately adjacent the knife 7 and provided with an anti friction disk 11 mounted in or on said face to facilitate the passage of work over it. The top surface of the saddle is inclined baclnvardly and its rear portion slotted or recessed for the reception of the upper end of a. lever 9 pivoted at 9 to the upper end of the post. (i. The lower end of said lever abuts on the upper end of the reciprocable bar 9 which is likewise slotted for its reception and the spring 8" normally maintains the saddle in contact with the lever, thereby holding said lever in engagement with the bar 9. With this construction it is possible for the saddle to move dmvnwardly in order to permit of the passage of an abnormally large body of material, although at all times it remains in perative engagement with the bar 9 through the lever t) and receives vibratory movement therefrom.

Connected to the rear portion of the premher 5 by a pin 17 is a flat casing '12 so mounted to be free to vibrate or move to a limited extent in a plane toward or from the band knife, 7, although its motion is rewhose operative verticalrun is.

111g recessed for the reception of a recipro- I sisted and tpzfsoiue extent limited by a spring 13 which eirtends, in the case illustrated, be-- tween its lowerportion' and a set screw 14 adjustably mounted in the rear end of said member 5. It is obvious that by moving this screw up or down and retaining it in anyadjusted position by means of a set crew 15, the effect of the spring 13'upo'n the possible swinging of the casing 12 may lie-varied within certain limits. Said casing has bearings for a shaft 16,}which has "fixed to it ;within the casing a segmental or other eccentrically mountedweight 17, while outside -justably connected to said casing structure by a set screw 21. For the purpose of regulating the posit-ion of this hammer withthe utmost degree of nicety, I provide the casing with a socket 22 for the reception of the end of the hammer and mount in it a pair of co-acting wedges 23 and 24 whereby said hammer may be moved to any desired extent toward or from the knife 7; For the purpose of this adjustment there is formed on the structure 12 a lug 25 through which passes the adjusting screw of the wedge :23 whose larger end extends downward. The second wedge 24 has a projection from its smaller ,or lower end also passing through the lug 25v and threaded for the reception of adjusting and holding nuts as-shown. Both of these wedges are i mounted in an opening of the socket 22.80

that the wedge 24 is capable of engaging the rear end of the hammer in order toforce it toward the knife 7 when either of said wedges has been suitably moved. After adjustment the hammer is retained in any given position by means of the set screw 21.

As shown in Figs; 4 and 6, the hammer head is provided with a relatively deep recess for the free passage of the operative run 7 of the band knife, and its main portion or portions extend across the plane of said knife to engage or he adjacent an abutment hereafter described.

Extending horizontally from the post 2 of the frame are any 'desired number of arms 27, 27 and 28, of which the latter carries a pair of guards 29 and 30 for the inoperative vertical run of the knife 7 while which eirtends" verticallyfon that side of said knife opposite the hammer. The lower end of the clapper is immediately adjacent and normally in contact with the operative face ;of "sa,id hammer. f In addition the arm 27 cai-ries a. pair of knife guards 32 and 33'.

; ,j bvious that any blow struck by the hammer tends to cause an outward movemeat of the clapper 31, since this latter is supported ona hinge or pivot pin 34 and is a tension member 37 to the irearwardly projecting end of the arm 28. This block or abutmentis provided with anopening for the reception of the lower end of. the clapper 31 and also for the adjustable wedge 38 which is designed to slide between the outer face of the said clapper and the block under the action of a lever 39 fulcrumed or pivoted on the upper end of a b-ar 40. The opposite end of this lever is connected through a rod 41 with a foot treadle 42 and is normally held in the position shown by a spring 45 which in the present instancev is attached tolsaid treadle.

A'set' screw 43, mounted in a suitably formed lug 44m? the wedge 38 so as to engage the b lock -36, serves to limit the distance which said wedge may be lowered under the action of the lever 39,-for said block forms an abutment between which and the clapper 31 the wedge 38 may be inserted 1n order to normally prevent deflection orv swinging outward of the lower end of said clapper under the action of the hammer 20 and of the spring 35 It is evident that with the withdrawal of the wedge 38, the hammer 20 will, under the action of the spring 13 tend to move against and possibly strike the band'knife, even though the knife recess in said hammer be relatively deep, and in order to prevent this, I provide an adjustable abutment on the tension member 37 placed to co-act with a suitable structure carried by the casing 12. For this purpose I fasten to the tension member a block or projecting lug in which is a passage threaded for the reception of a headed screw or bolt 56 extending toward the casing 12 which is provided with a recess for the reception of a rawhide or rubber plug or block 57. These various parts are so 'arranged that the head of the screw 56 1s 1n such a position as to be engaged by the plug .57 whenever the casing 12 moves nearer than a predetermined amount toward the band knife.- It is understood that suitable thesccond serves to support' a clapper 31 1 set screws or other equivalentmeans are provided formaintaining the screw 56 and the block or rod 57 in an given posit-ions.

Under operating con itions the band knife is driven at a high speed with its vertical run 7 moving upwardly, while in addition the pulley wheel 18 and with it the shaft 16 are also turned at a high rate of speed. This causes revolution of the segmental or eccentrically mounted weight 17 on said shaft,-so that this and the easing structureliZ, are given a limited vibratory movement depending to a slight extent on the-adjustment of the spring 13 but mainly upon the mass of the Wei ht 17 and the speed of 'the shaft 16. 'lh rod 9, which is operatively connected to t fieeasing structure as heretofort described, is thus caused to rapidly reciprocate and through the lever 9 impart a vibratory or vertical reciprocating movement to the work supporting saddle 10 which engages its upper end. Such a movement of said saddle facilitates or renders possible the free passage over it of the shoe to be trimmed, which is supported in the position shown in Fig. 5, and at the same time the saddle is free to move downwardly away from the hammer and clapper for an abnormal distance to permit of the passage of unusually thick bodies of material. The disk 11 also helps to render easy the passage of the work over the saddle,

as it materially reduces the friction.

When it. is desired-to operate on a shoe, a downward movement of the treadle 42 turns the lever 39 on its pivot and raises the wedge 38, thereby permitting thelower end of the clapper 31 to move away from the knife and hammer under the action of the spring 35, after which the shoe is placed in the position shown with the welt between-the clapper on one side, and the knife 7 and hammer on the other side, being supported largely on the saddle and to some extent by the duck bill plate58. lVith this disposition of parts, the stock which it is desired to trim off projects across the plane of the knife and the release of the treadle permits.-

the rising of the link-or rod'41 under the action of the spring 45, so that the wedge 38 is again inserted between the block or abutment 3G and theclapper '31, fo-rcing this latter into engagement; with the welt of the shoe operated on and clamping the latter between itself and the head of the hammer.

It will be seen from Figrl'that the clap per is wedge shaped, its lower end, which projects below the lower face of the block '36, beingi'elativcly thin and rounded in order that it may enter. and follow the crease When, therefore, the shoe is moved rmuwvardly, this enthmoving through the crease, serves both as a guide to direct and a stop to limit such movement. \Vhen the shaft in is driven as above noted, the

vibratory movement of the casing structure 12 1s nnpartcd to the hammer 20 so that this is caused to reciprocate in a horizontal line surplus material is trimmed from the shoe,

the main portion of the welt is caused to pass betwecn the face of the clapper 31 and the hammer 20 as above describcd and since' this latter is rapidly vilu'ated or reciprocated by the unbalanced structure formed by the shaft 18, the weight 17 and the casing 12, said welt is flattened and slightly extended; the clapper being unyieldingly supported so as toform a solid abutment, by means of the wedge 38 and the block 36. As above noted this block is unyicldingly held by the arm 27 and the tension member 37. The strength of the blow struck by the hannner, as well as the amount of reciprocation imparted thereto, may be regulated by adjusting the spring 13 or by inserting or removing some of the screw plugs of the weight 17.

The position of the hammer head relatively to the knife 7 and the clapper 31 may be ad'nsted b raisin or lowerin the wed e b h b 23 after the set screw 2.1 has been loosened; the hammer thus being forced toward the knife or being capable of movement away from the same as may be desired, after which it may be retained in position in the holder 22 by means of theset screw 21. As before noted the hammer is held from too close an approach to the knife by reason of the engagement of the screw 56 with the rod or plug 57.

The position of the clapper 31 when the wed ge 38 has been inserted, is determined by the adjustment of the screw 4?) carried by said wedge, since this is so placed that it strikes the top surface of the block 36 when the wedge has been forced down by the lever 39 to the extent necessary to bring and hold the clapper 31 in the desired position. The position of the saddle l0 relatively to the hammer 20 may be varied by the adjustment of the screw bolt 19 in the projection 17 as the longitudinal movement of the bar 9 turns the lever 9 on its pivot, and thereby either forces the saddle down or permits it to rise under-the action of the spring 8.

lVhile the'vibratory i'novemcnt ofthc cas ing 12 under operating conditions may be regulated as above noted, it is obvious that if desired, the portion 17 .of the casing structure, instead of being loosely attached to the member a by the pivot 17 as shown,

may be rigidly connected thereto. In such case this portion may be made in the form of a laterally flexible spring without departing from my invention.
